Specification of Letters Patent.

Patented Sept. 5, 1905.

Application filed October 12. 1904. Serial No. 228,205.

To all 117mm if lll/ftj/ conic/ ria:

Be it known that I, Janus E. )IANNIX, a citizen of the United States, residing at Lancaster, in the county of Garrard and State of Kentucky, have invented a new and useful Improvement in a Filter, of which the following is a specification.

My invention relates to a self-d raining filter adapted for use either in a building, water being supplied to the filter from any suitable source, or to a cistern, the filter being arranged in the cistern and the water supplied to the cistern passing through the filter.

The object of the invention is a device of this kind in which the water will be settled twice, once before passing through the body of filtering material and again after being liltered, and which will be self-draining, so that no water will be allowed to stand in the filter, but at the same time the sediment will be prevented trom escaping through the drains.

My invention consists in the novel featuresot construction and combination of parts hereinafter described, particularly pointed out in the claims, and shown in the accompanying drawings, in which Figure l is a side elevation of my device.

Fig. 2 is a vertical longitudinal section. Fig. 3 is a sectlon on the line 3 3 of Fig. 2. Fig. A is a section on the line a 4: of Fig. 2, the

charcoal being removed.

In constructing my device I employ a casing A, of any desired shape, size, and material,

in which is arranged a charcoal-receptacle B, supported above the bottom of the casing A by means of supporting brackets or legs B, and the bottom of the receptacle B is perforated, shown at B". The upper end of the receptacle B is closed by a water-receiving receptacle C, which [its snugly within the easing A and rests upon the receptacle B. The top (1 of the receptacle is flanged and lits over the upper edge or rim of the casing A, thus entirely closing the top of the casing. A supply-pipe l) is carried by the top C and discharges into the receptacle 0 adjacent one side of the same. An upwardly and downwardly open pipe E is carried by the bottom of the receptacle (1, extending upwardly into the said receptacle and is out of alinement with the supply-pipe l). The receptacle B is of less diameter in one direction than the easing A, and a discharge-pipe F, open at both ends, passes through the bottom of the casing A and extends upwardly between a side wall of said casing and the receptacle B. A siphon I (i is arranged in the pipe E, the short leg of the siphon passing through the pipe E and opening downwardlv into the receptacle 0 adjacent the bottom of the same, the long leg of the siphon passingdownwardly within the pipe E and discharging into the receptacle B. A similar siphon H is arranged in the lower end portion of the pipe F, discharging outwardly through the lower end of the said pipe and draining the casing A. Charcoal or any other suitable filtering material is placed in the receptacle B.

\Vater entering the pipe I) will fill the receptacle (J to the level of the top of the pipe E, through which it will pass into the receptacle B, discharging from said receptacle into the bottom of the casing A through the perforations B" and rising in the space of the casing A, in which is arranged the pipe F, will tlow into the upper end of the pipe and be discharged into the cistern. It will be obvious that sediment will settle first upon the bottom of the receptacle C, and all of the heavier particles will be prevented from passing into the filtering material .l. All the heavy particles which may be carried out of the lilter by the passage of the water therethrough will settle in the bottom of the casing-A while the water drains off through the pipe F. In order, however, to prevent water from standing in the receptacle U and also in the casing A continuously to the lcvelot' the pipes IQ and F, respectively, the siphonsti and II are employed, and this wil l drain oll the water without permitting the escape of the sediment, as would be the case if a mere straight drainage pipe or aperture were provided. The receptacle C can be readily and quickly removed, as can also be the receptacle B, and the parts can be cleaned and the filtering matter renewed without ditliculty. A. screen It is placed over the pipe E, but may of course be omitted it' not desired.

Having thus fully described my invention, what 1 claim as new, and desire to secure by Letters Patent, is-

1. A lilter comprising a receptacle adapted to contain liltering material, said receptacle having a perforated bottom, a water-receiving receptacle, a pipe extemling upwardly into the lastmentioned receptacle and opening downwardly into the liltering-receptacle, and the siphon arranged in said pipe, the short leg of the siphon extending into the water-receiving receptacle and adapted to drain the same into the first-mentioned receptacle.

ITO

2. A device of the kind described comprising a casing, areceptacle arranged in said casing and having a perforated bottom elevated abovethe bottom of the casing, a Water-receiving receptacle resting upon the receptacle first mentioned, a pipe carried by the bottom of the water-receiving receptacle and extending' upwardly into the said receptacle and opening downwardly into the receptacle first 1O mentioned, a vertically-arranged pipe opening downwardly through the bottom of the casing and extending upwardly into the casing between the first-mentioned receptacle and a wall of the casing, a siphon in each pipe, as and for the purpose set forth.
